DMC3-FM2 is member of DMC3 Earth observation constellation. The acronym DMC stands for Disaster Monitoring Constellation. Each DMC3 spacecraft weighs 447 kilograms, or 985 pounds, at liftoff and uses an electric xenon-fueled propulsion system for attitude control and orbital maneuvers. The satellites carry electro-optical cameras with one-meter (3.3-foot) resolution in black-and-white mode, the highest-resolution Earth observing spacecraft ever built by SSTL. The three-satellite Earth observing network can image the same place on Earth at least once per day.
